对元素周期表 s 区和 p 区元素的研究不断分离出具有有趣电子结构的不寻常化合物，我们在这些努力中的工作是永恒的。主族化合物经常挑战和扩展传统的键合模型，并且在许多情况下引发了关于路易斯结构表示的争论。无可争议的是，主族元素有能力以几十年前不明显的方式影响化学的多个领域。事实上，很明显，某些主族系统甚至可以引发以前为过渡金属保留的反应性趋势。这导致了主族元素的各种新应用，包括主族元素在氧化还原催化中的快速发展，以及用于开发功能材料的主族策略。以这些事实和新趋势为背景，我们很高兴推出有机金属学特刊“主族元素的有机金属化学”，其中收录了由顶尖化学家撰写的 37 篇文章，他们提供了该领域的及时更新。这些报告为主族多重键、低价主族化学、路易斯酸/碱化学、主族中心配体以及新型主族材料的化学提供了令人兴奋的新见解。主族化学中反复出现的主题是重主族元素化合物与其碳基类似物的结构和键合的比较。虽然烯烃和炔烃是有机化学中常见的官能团，但较重主族元素的元素-元素多重键的合成并非易事，并且这些化合物通常更具反应性和空气敏感性。事实上，碳-碳多重键的普遍性常常让我们忘记，碳的化学行为对于第 14 族元素来说是例外，而不是规则。
Research on the elements in the s-and p-blocks of the Periodic Table continues to result in the isolation of unusual compounds with interesting electronic structures our work in these endeavors is timeless. Main-group compounds have often challenged and expanded traditional bonding models, and in many cases have sparked debate over the representation of Lewis structures. What is not debatable is that main-group elements have the capability to impact multiple areas of chemistry in a way that was not apparent several decades ago. Indeed, it has become clear that certain main-group systems can even elicit reactivity trends that were previously reserved for transition metals. This has led to a variety of new applications for the main-group elements, including the rapidly evolving prevalence of main-group elements in redox catalysis, as well as main-group strategies for the development of functional materials. With these truths and new trends as a backdrop, we are happy to present an Organometallics Special Issue,“Organometallic Chemistry of the Main-Group Elements,” in which we feature a collection of 37 articles contributed by leading chemists who provide a timely update on the field. These reports offer exciting new insights into the chemistry of maingroup multiple bonds, low-valent main-group chemistry, Lewis acid/base chemistry, main-group-centered ligands, as well as novel main-group materials.A recurring theme in main-group chemistry has been the comparison of structure and bonding in heavy main-groupelement compounds with their carbon-based analogues. While alkenes and alkynes are common functional groups in organic chemistry, the synthesis of element− element multiple bonds of the heavier main-group elements is not trivial, and these compounds are typically more reactive and air-sensitive. Indeed, the ubiquitous nature of carbon− carbon multiple bonds has often led us to forget that the chemical behavior of carbon is the exception, not the rule, for the group 14 elements.
